Title: Optical disk medium
Inventor: IWAMOTO TOSHITAKA
IPC: G11B7/24035
Filed: 1988-12-01
Abstract: PURPOSE:To prevent the cost of a servo control circuit from increasing by dividing a recording layer to plural zones in a radial direction and constituting the recording layers of the respective zones in such a manner that these layers vary respectively in the reflectivity of light. CONSTITUTION:The recording layer is divided to the plural zones 21 to 26 in the radial direction of the optical disk medium 1. These zones are so constituted that the zones 21, 23, 25 have the same reflectivity with respect to the light beam spot projected thereto and the zones 22, 24, 26 are different in the reflectivity from the zones 21, 23, 25 and are the same in the reflectivity. The output of a photodetector which receives reflected light changes every time when the light beam spot crosses the respective zones 21 to 26 in the case of moving a carriage at a high speed and, therefore, the moving speed and moving distance of the carriage can be calculated by utilizing the change point of this output. Counting of 100 track error signals is resulted at every crossing of one zone if the number of tracks per zone is assumed to be 100. The need for improving the frequency characteristics of the servo control circuit is eliminated.

Title: Semiconductor memory
Inventor: ARAI SANENARI
IPC: G11C7/10
Filed: 1998-10-28
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor memory in which a memory cell part can be tested in a short time. SOLUTION: A read data/comparison data select circuit 107 outputs either parallel data WT0-WT7 before written to a memory cell part or parallel data CR0-CR7 read out from the memory cell part. The CR0-CR7 from the circuit 107 or data CW0-CW7 from a serial/parallel converter circuit 102 are compared with data RT0-RT7 read out from the memory cell part by a comparison circuit 106. When the RT0-RT7 and comparison data all agree, the comparison circuit 106 outputs an 'H'. When the data disagree, the comparison circuit outputs an 'L'. Because of two comparison data, i.e., data CW0-CW7 and CR0-CR7, the number of times for setting the comparison data can be reduced, whereby a time required for testing the semiconductor memory is shortened.

Title: Fixture member
Inventor: NAKAMURA HIROFUMI
IPC: E04F15/00
Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To secure a fixture member that can hardly damage a tonque piece and has a small difference in level with the flooring by executing a body part adjacently with an end of this flooring, and covering this flooring end by this specific thickness tonque piece integrally installed in the body part. SOLUTION: A tonque piece 12 is combinedly connected to the upper part of a body part 11 of a fixture member 10 consisting of a soft material such as soft synthetic resin of polyvinyl chloride or the like and gum or the like on the whole. Thickness h2 of this tonque piece 12 is set to a range from 0.5 to 1.5mm or so, and in time of manufacturing, this tonque piece 12 is formed into a state of being tilted downward. Then the body part 11 is set up adjacently with an end of the executed flooring 14 and attached tight to a floor face, covering this end of the flooring 14 closely by the tonque piece 12. If so, a difference in level with the flooring 14 becomes lessened enough, and thereby it will not hinder to ambulation at all.  In this connection, since this tonque piece 12 is apt to be curly, it is energized on the flooring 14, it has such an advantage as being hard to get from the flooring.

Abstract: PROBLEM TO BE SOLVED: To precisely control amount of electrons to be accumulated in a memory element by giving four kinds of memory conditions having four kinds of threshold values to each memory element, previously aligning all threshold values to the highest threshold value as each threshold condition and thereafter extracting the predetermined amount of electrons accumulated in the floating gate electrode of each memory element. SOLUTION: The threshold values of memory cell are defined as the condition 1 to condition 4 from the lower threshold. Before the writing operation, electrons are extracted from the floating gate electrode 13 of each memory cell, the threshold values of all memory cells are almost converged to the condition 1, next electrons are supplied at a time to the floating gate electrode 13 and thereby the threshold values of all memory cells are set to the condition 4. The writing operation is continued until a predetermined threshold can be attained by comparing the threshold of memory cell with the predetermined threshold after electrons are extracted from the floating gate electrode and then the predetermined write period has passed. Thereby, the threshold can be set in the small step and 2-bit can be stored easily.
